As
mcampo2501 said there are no such thing as good numbers or bad numbers provided you are tracking them historically. At my last group we had a 23 person centralized BDC for 10 stores and I tracked everything down to the smallest detail. We created internal training aids and process maps to drive the numbers you are referring to.
It is important to note that benchmarks can quickly become obstacles for continued improvement. Once they are hit with regularity, people will take their foot of the gas. That is why it is important to communicate
"Where you are at versus where you have been" more than you communicate "
Where you are at versus a made up benchmark."
Also, relying on what another dealer said they did can be misleading for a number of reasons:
- How pure is their reporting? They could be isolating customers, sources and other outliers.
- Their procedures for CRM data accountability are going to be totally different than your store/groups.
- How much money they spend and their effectiveness in marketing. All things being equal if you were to compare the results of 2 dealers using the same source in the same market the dealer that spends more or markets more effectively
should convert better.
- Dealerships market and customer base. As an example think of the variance in the numbers between a metro versus a rural dealership.
- Number of quality sales people with over 90 days of tenure. This is probably one of the best leading indicators for overall sales in a dealership and will impact all areas of your sales funnel.
Here is what I considered benchmark (note this was only shared when absolutely necessary):

Note: this is for all sources: phone, internet, 3rd party over a rolling 30 day period, giving you an overall appt to sale of 25%. Also, some of you may say a 50% show rate is low. Consider that this is only what is tracked and recorded in the CRM, the true number will always be higher - as certain customers won't get logged as shown.
That is why the best approach is to build your own reliable reporting, seek out the variation that causes your gains/losses and drive your team to a process that gives you consistent numbers. For more info I wrote an article about improving show rate and sold rate on my site called
